RapidFix adhesive is an advanced polymer that can quickly - sometimes instantly - bond most materials to themselves or another material. The RapidFix welding powder is a complementary formulation that enables even stronger bonds, and can repair holes, cracks, and gaps. For some applications, the welding powder can even function like solder or traditional heat welding. Areas treated with RapidFix adhesive can be filed, sanded, and painted almost immediately.
